US 2024/0179529 A1 · MESSAGE TRANSMISSION METHOD AND COMMUNICATION APPARATUS

Abstract

Examples of message transmission methods and apparatus are described. In one example, a message transmission method includes that a first network device receives a first message from a terminal device, where the first message includes a resume cause value and an integrity check code. The integrity check code is generated based on the resume cause value, the terminal device is in an inactive state, and the resume cause value is a resume cause indicated by a higher layer or a radio resource control (RRC) layer. The first network device sends a second message to a second network device, where the second message includes the resume cause value and the integrity check code. The second network device is a network device that stores a context of the terminal device.

Dependent claims

A method for message transmission, comprising:

receiving, by a first network device, a first message from a terminal device, wherein the first message comprises a resume cause value and an integrity check code, the integrity check code is generated based on the resume cause value, the terminal device is in an inactive state, and the resume cause value is a resume cause indicated by a higher layer or a radio resource control (RRC) layer;
and
sending, by the first network device, a second message to a second network device, wherein the second message comprises the resume cause value and the integrity check code, and the second network device is a network device that stores a context of the terminal device.

A method for message transmission, comprising:

receiving, by a second network device, a second message from a first network device, wherein the second message is sent by the first network device when the first network device receives a resume cause value and an integrity check code that are sent by a terminal device, the second message comprises the resume cause value and the integrity check code, the terminal device is in an inactive state, and the resume cause value is a resume cause indicated by a higher layer or a radio resource control (RRC) layer;
and
checking, by the second network device, the integrity check code by using the resume cause value.

An apparatus, comprising:

one or more processors;
and
one or more memories coupled to the one or more processors and storing programming instructions for execution by the one or more processors to cause the apparatus to perform operations comprising:
receiving, by a first network device, a first message from a terminal device, wherein the first message comprises a resume cause value and an integrity check code, the integrity check code is generated based on the resume cause value, the terminal device is in an inactive state, and the resume cause value is a resume cause indicated by a higher layer or a radio resource control (RRC) layer;
and
sending, by the first network device, a second message to a second network device, wherein the second message comprises the resume cause value and the integrity check code, and the second network device is a network device that stores a context of the terminal device.
